Tay PJM, Pek PP, Fan Q, et al. - Given that in Singapore, 70% of OHCA occur in residential areas, and are associated with poorer outcomes, researchers investigated if OHCA survival could be improved with an interventional bundle consisting of Save-A-life (SAL) initiative (cardiopulmonary resuscitation (CPR)/ automated external defibrillator (AED) training and public-housing AED installation), Dispatcher-Assisted CPR (DA-CPR) program and myResponder (mobile application). In this pilot study, data from initial implementation of a stepped-wedge, before-after, real-world interventional bundle in six selected regions were assessed. The analysis included 1,241 patients (Intervention: 361; Control: 880). Outcomes revealed significant improvement in survival with the OHCA interventional bundle (SAL initiative, DA-CPR, myResponder) and support its scaling up as a national program.
